To lift your confusion, you might want to consider to educate yourself about the "Internet Rules". Especially Rule 63:
You must be registered to see the links
These count as meme's nowadays, however they are used on a daylie base. Except a few.
I already knew about that rule, but I had never thought about it so thanks.
But I still think that it's strange (not because I think you're wrong):
1°. Cookie is the only character of this artist that has a gender bended version, not only some pictures but also some videos.
2°. I think it's unusual to an artist create too much arts with the "original character" gender bended (I know that there is some artists that do some things like this, but it's just one or too arts not too much)
3°. I feel strange for thinking that there is too versions of a character that was originally one gender. I understand that it can be a alternative universe or just a joke, but I still can't stand that idea of another gender for that character because for me it's an idea of a character that is transgender and I particularly don't like that idea (sorry for not liking too much futas).
I just want to understand that correctly because I've never saw the artist explaining about why he decided to create that because the videos with the female version has a voice actress and for the male version has a voice actor for me it's too professional for something that it's so simple.
